While this is an interesting approach, I'm afraid it will
be at the expense of robustness. Let's say I've messed up
my /netbsd and load a rescue kernel from floppy, DOS or
network, but still want my normal root fs (ie, "boot -a"
on i386). The bootloader doesn't know about the hard disk
filesystem, doesn't have disk support at all or the
root disk controller is not supported by the firmware.
Further, if some work can be done in the bootloader or
in the kernel, I'd always prefer to do it in the kernel.
It has less size restrictions, a bigger set of support
functions and debugging support. Debugging a boot loader
is a PITA.
